Abstract
Methods and apparatus useful in automated performance of immunoassays, in some preferred embodiments, relying upon the sandwich immunoassay technique, are described. Each rack of reaction tubes is uniquely identified by an optical identifier disc which is read by the automatic controller. The assays are performed at two stations which configuration thereby permits arrays to be run on a second rack of reaction tubes while the first rack is in process. The cooperation of the identifier disc and the automatic controller minimizes operator error and helps improve the reliability of the data obtained.
